CONTEC E12 Digital Touch 12 channel ECG Machine ECG Electrocardiograph Wifi

The device is an electrocardiograph which can collect 12-lead ECG signal simultaneously and print ECG waveform with thermal printing system. It features in, recording and displaying ECG waveform in auto / manual mode; measuring, analyzing and diagnosing ECG waveform parameters automatically; prompting for “Lead off” and “Lack of paper”; optional interface language (Chinese / English, etc.); built-in lithium battery, AC / DC; selecting rhythm lead freely to observe abnormal heart rhythm; case database management.

1)Display with 1280*800 dots 10.1 inch high resolution color LCD, operate either by touch screen or function buttons, which is convenient and quick.

2)Sync collection for 12-lead ECG, support for 12-lead and Cabrera-lead waveform display, adopt digital signal processing technology and get high-quality ECG via power frequency filter, baseline filter, EMG filter and Low-pass Filter for ECG signals.

3)Display of 3/6/12-lead ECG waveform on one screen, and HR value, print mode, sensitivity, paper speed, filter state, clock, battery level, background gridlines, measured data and interpretation information, etc. Prompting function for lead-off and overload, system working state.

4)The device can be powered either by AC or DC(can adapt to 50/60Hz AC frequency), with built-in rechargeable lithium battery and charging circuit, perfect battery overcurrent and overvoltage protection circuit.

5)In optimal DC state, up to 10-hour standby time, continuous print more than 3-hour, record up to 1000 ECG waveform(commonly, it is 3s case), which meets the requirements of visiting a patient at home and body examination.

6)Built-in thermal printer, support for Auto M*N, Auto M*N+1, Auto M*N+2, Auto M*N+3, rhythm M line, manual and other printing modes and formats.The printed content contains time, paper speed, sensitivity, calibration signal, name of lead, filter state and patient’s information. Information including printed waveform length, output measurement parameter, diagnostic conclusion, superposition QRS waveform, histogram, trend chart and interval list, can be set, and with time print function and auto arrhythmia print function, which meets different requirements.

7)With the functions of auto-measurement and auto-interpretation for routine ECG parameters, provide measurement results and auto-diagnosis conclusion for HR, PR Interval, P Duration, QRS Duration, T Duration, QT/QTc Interval, P/QRS/T Axis, R(V5), S(V1), R(V5)+S(V1) amplitude, Cornell Index, etc. which reduces the doctor’s burden.

8)The built-in large-capacity memory can store at least 4000 medical records, making it easy for doctors to review medical records and statistical information.

9)Historical medical records can be reviewed, inquired, modified, transmitted, printed, lead correction, exported to other electronic file formats (dat, pdf, xml, bmp, jpeg, png etc.).

10)Multi-language(Chinese, English) interface and report. Full touch screen with buttons operation, built-in virtual keyboard, support Chinese and English input methods.

11)With Wi-Fi wireless communication function.With functions of  LAN, USB cable transmission. Automatically upload cases, download reports and print them.
